Title: Magnetic recording and reproducing device
Inventor: AZUMA KAZUKI
IPC: G11B15/467
Filed: 1987-09-30
Abstract: PURPOSE:To reproduce without executing an automatic tracking at the second and subsequent reproducing by learning once the most suitable tracking adjusted value and storing it in a memory at the time of reproducing a video signal stored on a magnetic tape. CONSTITUTION:At the time of reproducing the video signal, when identification information to coincide with a device number memorized in a control track is not recorded, a control means 1 allows the automatic tracking to be executed, allows a memory 7 to store the tracking adjusted value at that time and allows the control track to record the identification information composed of the recorder number and a magnetic tape address. When the identification information to coincide with the memorized recorder number is recorded, the tracking adjusted value is read out of the address of the memory 7 suited to the recorder number in the identification information and a tracking action is executed. Thus, by recording the identification information only once, the reproducing can be executed without giving an automatic tracking instruction at the second and subsequent reproducing.

Title: Gold-oxide composite
Inventor: HARUTA MASAKI
IPC: C09C3/00
Filed: 1991-08-30
Abstract: PURPOSE:To obtain a highly active catalyst without requiring complicated operation for ultra-fine pulverization even when gold is used as an active seed by using a support coated with gold or a fine gold particle as a carrier and supporting transition metal oxide on the surface of the carrier in a dispersed state. CONSTITUTION:As a carrier supporting metal oxide, a fine gold particle or a support coated with gold is used. A soluble or insoluble compound of gold is dissolved or dispersed in water as a gold precursor and a soluble salt of a transition metal component to be supported is added to this aqueous solution or dispersion. The aqueous solution or dispersion is evaporated and the evaporation residue is baked in air. By this operation, the soluble or insoluble compound of gold is changed to a stable metal state and the hydroxide or water-soluble salt of the transition metal component supported on the surface of the gold particle or the gold coated support is changed to an oxide form. By this method, a gold-oxide composite is obtained without ultra-finely dividing gold and extremely useful as a catalyst having high catalytic activity.

Title: Optical reception circuit
Inventor: TANAKA JIRO
IPC: H04B10/50
Filed: 1986-10-16
Abstract: PURPOSE:To contrive to simplify the circuit constitution by constituting the titled circuit by a photoelectric conversion element, a current/voltage converting circuit, an AC amplifier circuit, a waveform shaping circuit and an output buffer. CONSTITUTION:An optical current flows to a photodiode PD in response to an optical signal and converted into a voltage by a resistor R1, but the voltage signal is weak. The signal is amplified into an AC signal with a proper amplitude by 3-stage of AC amplifier circuits W1-W3 and passes through Schmitt circuits W4, K5 to be a rectangular wave. Further, the result is inverted and becomes an output Vout in response to the existence of light. Since the constitution of the block applying photoelectric conversion to the input signal and converting it into a voltage signal is very simple and AC amplification is adopted, the effect of a dark current of a photodetector and of a DC external light are eliminated and the effect of the dark current change due to the temperature change is excluded.

Abstract: PURPOSE:To deliver orientation depending upon the temperature of formation to a single crystal silicon island, and to obtain a desired orientation by periodically turning laser beams ON-OFF by an optical chopper and alternateIy shaping sections not melted and molten single crystal sections into a nonsingule crystal semiconductor island. CONSTITUTION:SiO2 such as SiO2 2B is formed through a vapor growth method under the state in which a polycrystalline silicon island 4A is left selectively through a photoetching method, and SiO2 2B on the polycrystalline silicon island 4A is removed selectively by using the photoetching method again. When the polycrystalline silicon island 4A acquired in this manner is irradiated with laser beams L while laser beams L are turned ON-OFF periodically by an optical chopper, the length lA of molten single crystal sections 5 or non-molten polycrystalline silicon 6 can be set arbitrarily by chopper frequency. since the orientation of polycrystalline silicon formed through a decompression chemical vapor growth method depends upon a temperature range of 550-750 deg.C, the surface azimuth of a single crystal silicon island can be determined through laser irradiation when the polycrystalline silicon island having the desired orientation is shaped previously through the method.
